Summary

• Chewbacca's first adventure was likely fighting against the Trade Federation's repeated attacks on his homeworld of Kashyyyk, showcasing his rebellious spirit and dedication to protecting his people.
• Chewbacca was present for the Battle of Kashyyyk and witnessed the Trade Federation's incursions over two decades, making him a seasoned warrior before meeting Han Solo.
• Chewbacca's early experiences as a rebel fighter against an external power laid the foundation for his later involvement with the Rebel Alliance and his willingness to stand up against the Empire.

Chewbacca was committed to a life of adventure when he joined Han Solo, and Star Wars has finally hinted at his first adventure before meeting his closest friend. Chewbacca was 200 years old for his first appearance in the original Star Wars film, making him middle-aged with an average lifespan of 400 years. This means Chewbacca could have had countless adventures over a long life before meeting Han in Solo: A Star Wars Story. However, a new Star Wars reference book suggests that Chewbacca had his first real adventure only a few decades before swearing a life debt to Han.
Star Wars: The Secrets of the Wookiees by Marc Sumerak chronicles the history of the Wookiees in the Star Wars universe, including events that would have affected Chewbacca's life. This paints a better picture of the Wookiees leading up to the Clone Wars while expanding on the villains of the Star Wars prequel trilogy. These new facts reveal more about Chewbacca's life and his most likely adventure before his friendship with Han.
